CBS (CZ) accelerator is a widely used rubber vulcanization accelerator designed to support faster curing, better scorch safety, and stable processing in many rubber compound systems. At Henan GO Biotech Co., Ltd., we present CBS as a practical formulation option for technical teams that need balanced processing performance and vulcanization efficiency.
CBS, also known as N-cyclohexyl-2-benzothiazolesulfenamide, is an accelerator used in rubber compounding to help control the vulcanization process. Its role is to improve curing efficiency while maintaining a useful processing window for mixing, shaping, and handling.
This product is commonly applied in natural rubber, reclaimed rubber, and vinyl synthetic rubber systems, and it performs especially well in SBR-based formulations. It can be used alone or combined with other accelerators according to formulation goals.
For industrial buyers and formulation engineers, CBS is typically selected when the target is a balanced combination of curing speed, scorch resistance, and overall process stability.
| Chemical name | N-cyclohexyl-2-benzothiazolesulfenamide |
| Formula | C13H16N2S2 |
| CAS number | 95-33-0 |
| Appearance | Gray-white to light yellow powder or granules |
| Main benefits | Efficient vulcanization, scorch resistance, short curing time, low odor, anti-aging performance |
| Typical usage focus | Tires, footwear, hoses, belts, cables, and general industrial rubber products |
The product is solvent-soluble in benzene, dichloromethane, carbon tetrachloride, ethyl acetate, acetone, and ethanol, while it is insoluble in gasoline and water.
CBS helps accelerate the crosslinking reaction during vulcanization, so the compound can reach its target curing state more efficiently. The practical value of this mechanism is that the compound gains a faster cure profile without immediately sacrificing processing safety.
In formulation practice, this means CBS can support a wider processing window than very fast accelerators while still delivering efficient cure development. That is why it is often considered in systems that need both manufacturing control and output efficiency.
When combined with compatible accelerators such as D, DT, TT, or TS, CBS can be adjusted to meet different curing targets, provided the compound design and process conditions are evaluated together.
A practical comparison helps technical teams choose the right accelerator for the compound, rather than selecting only by price or name. CBS is usually valued for its balanced performance, while other accelerators may be preferred when a different cure speed or processing behavior is required.
| Item | CBS (CZ) | General comparison point |
|---|---|---|
| Scorch safety | Good | Often chosen when processing safety matters |
| Cure speed | Efficient | Typically balanced rather than extremely fast |
| Application fit | Natural rubber, reclaimed rubber, SBR systems | May vary by polymer and processing target |
| Formulation flexibility | Can be used alone or in combination | Useful for compound adjustment and optimization |
Neutral judgment: CBS is not the only suitable accelerator, but it is a practical choice when a formulation needs a balanced mix of curing efficiency, scorch resistance, and processing stability.
CBS accelerator is widely used in industrial rubber products where consistent vulcanization behavior is important. Common application areas include:
Because it has a bitter taste, it is not suitable for food-related products.
CBS is especially relevant for natural rubber, reclaimed rubber, vinyl synthetic rubber, and SBR-based systems.
The dosage should be evaluated together with the compound structure, curing target, and processing window.
The accelerator should be assessed against other ingredients in the formula to avoid unexpected curing behavior.
Mixing temperature, curing conditions, and production speed should be aligned with the selected accelerator system.
These considerations are important because the same accelerator can behave differently depending on the complete rubber formulation and production environment.
As a chemical engineering company focused on product development, manufacturing, and trade, Henan GO Biotech Co., Ltd. supplies rubber additives with an emphasis on technical consistency and industrial use. For CBS accelerator sourcing, B2B customers often need more than a product name; they need support for selection, matching, and supply continuity.
The company’s experience in chemical materials, quality control, and stable production supports buyers who are evaluating formulation options for rubber processing. OEM options are also available according to customer requirements.
This approach is aligned with the company principle of technology innovation, quality first, and win-win development, while keeping the focus on practical industrial needs.
For rubber formulators seeking a practical accelerator with balanced vulcanization behavior, CBS (CZ) remains a relevant option for technical evaluation. Henan GO Biotech provides this product with a focus on industrial application, formulation support, and B2B supply needs, helping customers make more informed choices for stable rubber processing.
